[OpenMap Users] Map format

Hi! I'm exploring OpenMap in an attempt to plot position data from several airborne vehicles at once and follow them at close range (about 1:50000), and I have some questions when it comes to using OpenMap with various data formats.

Is it possible to use scanned maps in OpenMap? If so, what tools do I need, and how do I go on about it? (Preferably in short easy steps.) Is it possible to accomplish viewing scanned maps in OpenMap using only freeware? I have heard about GeoTiff, but I'm not sure if anyone has picked up on Don's challenge: <http://openmap.bbn.com/mailArchives/openmap-users/2002-06/0901.html>. I know I'm too small for such a task :)

I have also access to digital map data on ESRI Shape format 1:50000, but it is pre-projected (ref. FAQ 9.10). Is there any way of converting pre-projected shapefiles to lat/long format, or do I have to go shopping?

BTW I'm exhilarated by the tremendous versatility of OpenMap!
